The LCM of 168,931,349,896 is 124768896.
Find LCM of 168,931,349,896 with Prime Factorization
| 2 | 168, 931, 349, 896 |
| 2 | 84, 931, 349, 448 |
| 2 | 42, 931, 349, 224 |
| 7 | 21, 931, 349, 112 |
| 3, 133, 349, 16 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 7 x 3 x 133 x 349 x 16 = 124768896
Therefore, the lowest common multiple of 168,931,349,896 is 124768896.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
168 x 931 x 349 x 896 = 48909407232
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
168 : 1, 2, 3, 4, 6, 7, 8, 12, 14, 21, 24, 28, 42, 56, 84, 168
931 : 1, 7, 19, 49, 133, 931
349 : 1, 349
896 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 128, 224, 448, 896
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 168,931,349,896, is 1.
Now, the common factors can be found like this.
168:2x 2x 2x 3x 7
931:7x 7x 19
349:349
896:2x 2x 2x 2x 2x 2x 2x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 7x 7 = 392
Therefore, the value for common factors is 392.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 48909407232/(1x392)
LCM = 48909407232/392
LCM = 124768896
Thus, we can understand that the LCM of 168,931,349,896 is 124768896.
